EIN for LLC: What It Is, Why You Need One, and How to Get It

An EIN is one of the first things most LLCs need after formation. Here’s what it does, whether your LLC needs one, and the fastest ways to get it — including having your formation service file it for you.

What Is an EIN?

An Employer Identification Number (EIN) is a nine-digit number issued by the IRS that identifies your LLC for federal tax purposes — similar to a Social Security number, but for a business. It’s sometimes called a Federal Tax ID Number.

Why Your LLC Needs an EIN

Most LLCs need an EIN to operate normally. You’ll typically be asked for one when you:

  • Open a business bank account
  • Hire employees
  • File federal and state business taxes
  • Apply for business licenses or permits
  • Apply for business credit or loans

Single-member LLCs with no employees aren’t always required to have an EIN by the IRS, but most banks and vendors will still ask for one — so it’s worth getting regardless.

Good to know: Applying for an EIN directly through the IRS is free. Formation services charge a fee for this step because they handle the paperwork and submit it correctly on your behalf, which is useful if you’d rather not deal with the IRS system yourself.

How to Get an EIN for Your LLC

You have two practical paths:

  • Apply yourself, for free, directly with the IRS — via the IRS’s online EIN application if you have a Social Security Number or ITIN. Processing is usually immediate online, or by mail/fax if you’re a non-US resident without an SSN.
  • Have your LLC formation service file it for you — most formation providers offer EIN filing as an add-on (or included) service, handling the paperwork so you don’t have to navigate the IRS system yourself, which is especially useful for non-US founders.

Frequently Asked Questions

Is getting an EIN free?

Applying directly with the IRS is free. Formation services may charge a fee to file it for you as part of a package.

How long does it take to get an EIN?

Applying online directly with the IRS is typically immediate if you have an SSN or ITIN. Applications by mail or fax, or through a provider, can take longer.

Can a non-US resident get an EIN?

Yes. Non-US residents can get an EIN without an SSN, though the process is more involved — this is where a provider like Doola can help.

Do I need a new EIN if I change my LLC’s name?

Generally no — changing your LLC’s name doesn’t require a new EIN, though you should update the IRS with your new business name.
